We present a new tweakable block cipher family SKINNY, whose goal is to compete with NSA recent design SIMON in terms of hardware/software performances, while proving in addition much stronger security ...
Secondly, we present MANTIS, a dedicated variant of SKINNY for lowlatency implementations, that constitutes a very efficient solution to the problem of designing a tweakable block cipher for memory encryption ...
Security Analysis In this section, we provide a short summary of the in-depth analysis we conducted on the security of the SKINNY family of block ciphers. ...

Then we present the first analysis of ForkSkinny, showing that the best attacks on Skinny can be extended to one round for most ForkSkinny variants, and up to three rounds for ForkSkinny-128-256. ...

Both techniques benefit from the highly biased sets of messages that are provided and that actually correspond to the encryption of various books in ECB mode. ...
The definition of the tweakey schedule of SKINNY implies that the round tweakeys of all the even rounds (similarly of all the odd rounds) are related together by linear relations. ...
